我正在构建人脸识别网络应用程序，使用react作为前端，使用node作为后端。项目参考。到目前为止，我已经构建了前端，我们必须手动添加128-d和json文件中显示的用户名称。Json文件：

接下来，我将通过提供写用户名和上传按钮的选项来自动化用户输入部分，上传按钮将直接将用户名和他们的128-d写入json文件。但我不知道如何使用特定的语法写入json文件，即使用节点在名称标签和描述符标签之后写入
有人能帮我如何使用node作为后端将新条目添加到json文件中吗？
如果json文件在您的文件系统中，则可以导入该文件；如果您将其作为字符串，则可以使用JSON.parse对其进行解析。然后像往常一样编辑对象。之后，您可以使用JSON.stringify将其字符串化。
